These approaches to achieving better health at a more predictable cost will be used in tandem with other cost-control measures, such as cost-shifting to employees, utilization of a private insurance exchange service, and other plan design options, Wells Fargo said.

Insurers are hot to trot to get into the private insurance game, as 47 percent of respondents said they’ll launch a proprietary private exchange by next year.

“We’re finding that employers are considering private exchanges and defined contribution strategies to manage rising costs,” said Nick Allen, national practice leader for Actuarial Services with Wells Fargo Insurance.

Product innovation and consumer engagement remain critical in creating a culture of smarter health care spending,” he said.
